1 clam. (o1. 11o- 1) This invention relates to encasing means for furnaces, and has for one of its objects the production of a simple and eificient means for obtaining quick and steady heat from a furnace and to obtain a maximum amount of heat fora maximum length of time in proportion to the fuel consumed by the furnace.

A further object of this invention is the production of a simple and efficient encasing means for hot air furnaces and the like, wherein the encasing means comprises a series of spaced bricks or blocks, to provide air spaces between the bricks or blocks and thereby obtain maximum heating results.

Other objects and advantages of this invention will appear throughout the following specification and claim.

In the drawing:

Figure 1 is a top plan view of the furnace, certain parts of the encasing means being broken away and the top or cap of the furnace being removed to illustrate the spaced arrangement of the bricks;

Figure 2 is a side elevational view of the furnace and encasing means; i

Figure 3 is an enlarged fragmentary top plan View of a portion of the encasing means, a portion of the furnace wall being shown in section.

By referring to the drawing, in detail, it will be seen that I9 designates a conventional hot air furnace which may be of any type of construction without departing from the spirit of the invention. The furnace is provided with the conventional damper and draft regulator I which may be of any suitable type. preferably provided with a forwardly protruding portion I2, the sides of which preferably diverge, as at I3, to conform to the ends of the bricks or blocks described in the following, and which provide the furnace encasing means. The protruding portion I2 is provided with a suitable fuel door I4, a suitable water pot I5 and an ash pit door I 6, in the front face thereof, al1 of the conventional type, to facilitate servicing of the furnace conveniently from the front thereof.`

In carrying out my invention, the furnace Il) is placed upon a suitable base Il which is of suitable size to support the furnace I0 and also to support the encasing means I8. The encasing means I8 comprises a series of layers of bricks or blocks I9. The bricks or blocks I9 are placed in layers one upon the other, the individual bricks or blocks I9 of one layer being arranged in staggered relation to the bricks or blocks of the adjacent layer. The layers of bricks are held to- The furnace I9 is gether by mortar or other plastic material 20 along their horizontal upper and lower edges, as shown in Figure 2.

It should be noted, however, that the individual bricks or `blocks I9 arespaced from each other at their ends to provide radiating air spaces 2| between the various bricks or blocks of each layer of bricks or blocks. The furnace I0 is provided with a dome-shaped top or cap 22 which preferably overhangs or ts snugly over the top layer of bricks or blocks I9, for decorative purposes, as shown in Figure 2, Suitable pipes 23 pass through the top or cap 22 from the furnace I0 and extend to suitable locations for delivering heat from the furnace to desired areas, in the conventional manner common to such furnaces.

The bricks or blocks I9 which form the encasing means are placed tightly against the exterior of the furnace IU, and the air spaces between the bricks or blocks I9 will permit the bricks I9 at the ends thereof to absorb heat from the furnace, thereby providingquick, long, steady and a maximum amount of heat in proportion to the fuel consumed. The air spaces or air pockets 2| particularly provide a quick heat from the furnace,

when needed so that immediate benefit may be obtained when the re is started, through the compound beneiit of the multiple air spaces 2|.

It should be noted that there is no air circulation from one pocket to the other, and that the air entering the pockets between the bricks or blocks will become heated, and although air may be dissipated to the atmosphere surrounding the casing to heat the area surrounding the furnace, the heat from the furnace will heat the ends of the bricks or blocks and pass out through the air pockets or escape-ways 2| between the bricks.

It should be understood that the bricks or blocks I9 may be of any suitable design or type Without departing from the spirit of the invention, but these bricks or blocks I9 are preferably concave on their inner faces 24 so as to snugly fit and conform to the contour of the outer face of the furnace. Furthermore, the air spaces or pockets 2| extend from the outer face of the furnace |0 to the outer face of the blocks I9 to provide a v maximum surface area for each block for the absorption of a maximum amount of heat. From the foregoing description, it will be noted that the present invention relates to the construction of the encasing means, whereby the air spaces I9 are provided and it is not desired to limit the invention to a particular type of furnace with which the encasing means is used.

It should be noted that the inner face of each brick I9 fits in contacting relation with the wall I of the furnace l0, throughout the entire length of each brick. Since the bricks contact the furnace wall and are spaced from each other at their ends, the bricks will be elciently and quickly heated along their inner faces because of the contact with the furnace wall, and the heat from the spaced ends of the bricks will heat the air which is within the air-escape-Ways or air spaces 2|. The air-:escapelways communicate A7directly`v with the outsideatmospliere.

Having described the invention, what I claim as new is:

In combination with a furnaceiofrthaconventional type, an encasing means formed 0f a plurality of layers of bricks encirclingthe :furnace from bottom to the top thereof, each Vlayer of bricks consisting of a plurality of bricks laid endto-end in spaced relation to provide air-f-escapeways extending from the outer wall of the furnacertothe exterior ofthe bricks yandebetweenft-,he bricks, the anw-escape-ways :communicating `.fat

their outer ends with the outside fatmosphere whichf surrounds the furnace, ltherinneruface of :eachbrickfitting in contacting relationthroughair escapes from between the bricks.
